- 0:41Today we are exploring one of the biggest moments in space
- 0:45history, the first moon landing in 1969.
- 0:49We will look at how the astronauts got there, what they
- 0:52did, and why it still matters. So let's get on with today's
- 0:56episode. Imagine planning a trip that
- 1:09takes three days, crosses more than 380,000 kilometers, and
- 1:14ends on a place no person had ever visited before.
- 1:18That is what the Apollo 11 mission did.
- 1:21It began with a huge rocket called the Saturn 5, which
- 1:25launched from Kennedy Space Center in Florida on July 16th,
- 1:291969. The Saturn 5 was taller than
- 1:32many city buildings and had three stages that fired one
- 1:36after another to push the spacecraft into space.
- 1:39On top was the spacecraft that carried 3 astronauts, Neil
- 1:44Armstrong, Buzz Aldrin, and Michael Collins.
- 1:47Here is a yes or no question to start us off.
- 1:51Did all three Apollo 11 astronauts step onto the moon?
- 1:58No, only Neil Armstrong and Buzz Aldrin walked on the moon.
- 2:03Michael Collins stayed in orbit around the moon alone in the
- 2:06command module, making sure everything ran smoothly while
- 2:11waiting for his crewmates to return from the surface.
- 2:14The Apollo 11 spacecraft had two main parts for the trip.
- 2:18The command module, which was the small cone shaped capsule
- 2:21where the astronauts lived during most of the mission, and
- 2:24the lunar module, which was the Lander used to go down to the
- 2:28moon and back up. The command module had a call
- 2:31sign or radio name called Columbia.
- 2:34The lunar module was called Eagle.
- 2:37Did you know these names were chosen by the crew and they used
- 2:40them constantly when talking with Mission Control in Houston,
- 2:43TX. The journey from Earth to the
- 2:46Moon took about 3 days. The astronauts guided their path
- 2:50using the onboard Apollo Guidance Computer.
- 2:53It was powerful for its time, but had far less memory than a
- 2:57basic digital watch or calculator.
- 2:59Today, the guidance computer used about 2 kilobytes of
- 3:03working memory to help keep the spacecraft on course.
- 3:07The crew also used star sightings, checking the
- 3:10positions of bright stars through a special window to
- 3:13confirm where they were. They did routine tasks, ate
- 3:16meals and space pouches, and sometimes looked back at Earth,
- 3:21which appeared as a round, colorful world in the blackness
- 3:25of space. Here comes a trivia question
- 3:27that teaches a new detail about space travel.
- 3:31How long does it take for a radio message to travel one way
- 3:34from the moon to Earth? About 1.3 seconds.
- 3:42That means when someone on the moon spoke to Mission Control,
- 3:45there was a short delay before anyone on Earth heard it.
- 3:49That tiny delay made careful communication even more
- 3:52important. On July 20th, 1969, Eagles
- 4:02separated from Colombia and began to descend toward the
- 4:06moon. Neil Armstrong and Buzz Aldrin
- 4:09piloted Eagle to a safe landing spot at 2017 Universal Time.
- 4:15Coordinated, they touched down in an area called the Sea of
- 4:18Tranquility. Neil Armstrong reported the
- 4:22Eagle has landed. The landing was careful and slow
- 4:26because the surface was dusty and uneven.
- 4:29After landing, they did safety checks to be sure the spacecraft
- 4:33was stable and everything was working.
- 4:36A few hours later, Neil Armstrong climbed down a ladder
- 4:41and stepped onto the moon's surface.
- 4:43He became the first person to do this, then Buzz Aldrin joined
- 4:48him. They moved carefully because the
- 4:50moon's gravity is about 1/6 as strong as Earth's gravity.
- 4:55This lower gravity made them lighter, but their suits were
- 4:58bulky and stiff, so they practiced measured steps.
- 5:02Did you know their space suits had layers for pressure,
- 5:05temperature control and protection from tiny, sharp dust
- 5:09particles? While on the surface, Armstrong
- 5:12and Aldrin collected rock and soil samples.
- 5:16They filled special bags with grey, powdery dust and small
- 5:20rocks to bring back for scientists.
- 5:22They set up experiments to 1 was a seismometer to listen for
- 5:27natural shaking in the moon's ground.
- 5:29Another was a set of special reflectors that bounced laser
- 5:33light directly back to Earth. These reflectors do not need
- 5:37power. They're like precise mirrors for
- 5:39laser beams sent from observatories.
- 5:42Here is a yes or no question about those experiments.
- 5:46Is there a mirror like device from Apollo 11 still on the moon
- 5:49that scientists use today to measure the Earth moon distance
- 5:53with lasers? Yes, the Laser Ranging
- 5:59retroreflector from Apollo 11 still works, and scientists use
- 6:04it to measure the distance to the moon with centimeter level
- 6:07accuracy. The moonwalk lasted a little
- 6:15over 2 hours. Armstrong and Aldrin worked
- 6:18through a checklist of tasks, sample collection, photography,
- 6:23experiment setup and documenting the site.
- 6:26They also planted a United States flag and left a small
- 6:30plaque on the Landers leg that recorded the date and their
- 6:33visit. The TV camera they set up sent
- 6:36live video back to Earth. Did you know hundreds of
- 6:39millions of people watched the broadcast on television, even
- 6:43though the video looked fuzzy and black and white?
- 6:46Here comes a trivia question that brings in a fresh piece of
- 6:49the story. Which ship picked up the Apollo
- 6:5211 crew after they splashed down in the Pacific Ocean?
- 6:59The aircraft carrier USS Hornet after re entering Earth's
- 7:03atmosphere. Their command module parachuted
- 7:06into the ocean on July 24th, 1969 and Navy divers helped
- 7:12bring them aboard the ship. Before we get to splashdown,
- 7:16there was still more to do. After finishing work on the
- 7:19surface, Armstrong and Aldrin returned to the Lunar Module and
- 7:23lifted off from the moon using its ascent engine.
- 7:27They met up with Michael Collins, who was orbiting in
- 7:30Columbia. The two parts docked together,
- 7:33the samples were moved into the command module, and the crew
- 7:37prepared for the trip home. Did you know the Lunar Landers
- 7:40lower section stayed on the moon and is still there today?
- 7:43Back on Earth, the crew faced one more careful step,
- 7:48quarantine. Because no one knew for sure
- 7:50whether moon dust might carry anything that could affect
- 7:54Earth's environment or health. The astronauts and some of their
- 7:57gear were kept in a sealed environment for about two weeks.
- 8:01Scientists examined the rock samples, dust and equipment.
- 8:06Nothing harmful was found, and the quarantine ended
- 8:09successfully. This step showed how serious the
- 8:13mission planners were about safety and science.
- 8:21Here is another yes or no question you might not have
- 8:24heard before. Did Apollo 11 carry a small
- 8:28piece of wood and fabric from the first airplane built by the
- 8:31Wright brothers? Yes, a tiny piece of wood and
- 8:38fabric from the 19 O3 Wright Flyer was taken along as a
- 8:42tribute to earlier pioneers of flight and then returned safely
- 8:46to Earth. The Moon rocks from Apollo 11
- 8:49taught scientists a lot. They found that the rocks are
- 8:53very dry and contain minerals also found on Earth, like the
- 8:57salt. This information supports the
- 8:59idea that the moon formed long ago for material that once was
- 9:03part of Earth. Although scientists continue to
- 9:06study the details. Did you know that three
- 9:09previously unrecognized minerals were discovered from the moon
- 9:13samples brought back by Apollo 11?
- 9:15Let's add one more trivia question that shares a new
- 9:18angle. How many people in total have
- 9:21walked on the moon across all Apollo missions?
- 9:2712 people. All of them were NASA astronauts
- 9:30who walked on the moon between 1969 and 1972 during the Apollo
- 9:36program. The footprints from Apollo 11
- 9:39are still there because the moon has no wind or rain to wash them
- 9:43away. There is no air moving across
- 9:46the surface. The marks can slowly change over
- 9:49very long periods, but they last far longer than footprints on a
- 9:53beach or a sidewalk on Earth. Equipment from Apollo 11 stays
- 9:58there, too, including parts of the Lander and the scientific
- 10:02instruments. Communication, navigation and
- 10:05teamwork made Apollo 11 possible.
- 10:08The astronauts trained for years.
- 10:11They practice climbing in and out of mock ups, using tools
- 10:15with thick gloves and working through problems calmly.
- 10:19Mission Control teams worked 24 hours a day, watching fuel
- 10:23levels, computer alerts and the spacecraft's path.
- 10:27Did you know that during the landing, the guidance computer
- 10:30showed warning codes because it was handling more tasks than
- 10:33expected and the team decided it was safe to continue?
- 10:42Before we wrap up, here is a quick recap.
- 10:45Apollo 11 launched on July 16th, 1969 on the Saturn 5 rocket.
- 10:52The crew was Neil Armstrong, Buzz Aldrin, and Michael
- 10:55Collins. Columbia was the command module
- 10:58in lunar orbit and Eagle was the lunar module that landed.
- 11:03Armstrong and Aldrin spent just over 2 hours walking on the Moon
- 11:07on July 20th, collecting samples and setting up experiments like
- 11:11the seismometer and the laser retroreflector.
- 11:15Hundreds of millions watched on TV.
- 11:17The crew rejoined Michael Collins returned to Earth,
- 11:21splashed down on July 24th, and were recovered by the USS
- 11:26Hornet. The mission was carefully
- 11:28planned, safely completed, and it gave scientists priceless
- 11:32samples and data. Today, the legacy of Apollo 11
- 11:37continues. Every time scientists bounce a
- 11:39laser off the reflector, every time students study moon rocks
- 11:43and museums, and every time we look up at the moon and know
- 11:47that people have been there and returned home.
- 11:49Grab. Your breakfast, feeling fine,
- 11:54adventures waiting, don't be late.
- 11:57Today's. The day we celebrate.
